library/io.m:
Add two new predicates.
The new predicate read_named_file_as_string reads in a named file,
and returns its contents as a single giant string. This is effectively
a combination of open_input, read_file_as_string, and close_input.
The new predicate read_named_file_as_lines reads in a named file,
and returns its contents as a list of strings, each containing
the contents one line (minus the newline char at the end, if any).
This is effectively a combination of open_input, read_file_as_string,
split_into_lines (see below), and close_input.
library/string.m:
Add a new function, split_into_lines, which breaks up a string into
its constituent lines, returning each line minus its newline.
This differs from the old split_at_char('\n', ...) in that it
expects the input string to end with a newline, and does not return
an empty string after a final newline. (If there *are* characters
after the final newline, it does return *them* as the final line.)
NEWS:
Announce the new predicates and function.
compiler/source_file_map.m:
Use the new functionality to simplify the code that reads in
Mercury.modules files.
tests/hard_coded/string_split.{m,exp}:
Add tests for split_into_lines.
